Abstract
The utility model relates to a positioning seat for a prefab end of an arc box, which is a positioning structure for controlling the precision of a segmental prefab connector of a reinforced concrete arch box. The positioning seat comprises a door-type frame including a concrete column, angle steels and a supporting rod; a steel plate is pre-embedded on the concrete column; a positioning angle steel is fixed on the steel plate; the supporting rod is welded with an end contact surface angle steel to form the door-type frame which is fixed on the positioning angle through screw bolts; and the end contact surface angle steel is mounted at an inclination angle according to the design of the end of the arc box. The angle steel of the connector of the arc box is connected with the end contact surface angle steel, and both ends of the an arc vaulting are provided with the positioning seats, so that the connectors of adjacent arc box segments are coupled together to avoid repeated measurements of connector angle steels of the positioning arc boxes, the key problems of control of the end of an arc segment, and the like are solved, and the precision of the connector of the arc box is guaranteed, so the construction quality is guaranteed.
Description
Technical field
The utility model relates to a kind of when striding the bigger bridge construction in footpath, for the location structure of reinforced concrete arch case prefabricate joint precision control.
Background technology
At present, adopt the bridge span footpath of cable lifting construction increasing, along with the increase of striding the footpath, the increase of segmental hoisting sections, the joint precision of prefabricated arch case becomes influence arch case lifting accuracy factors, and the arch case connects inaccuracy, and joint connects contact not exclusively, and then the even transmission of influence arch case axial force, influence safety and reliability that cable lifts.Mostly joint angle steel installing and locating when the arch case is prefabricated is to be fixed on the template of termination, the position that all needs repeated measurement termination template during each the installation, each error of measuring has caused the scale error of arch case termination, have a strong impact on the installation accuracy of its arch case, and repeatedly the workload of Ce Lianging is also big, and effect is not high.
Summary of the invention
The purpose of this utility model is the restive problem of the prefabricated precision of arch case that overcomes prior art for the box arch bridge work progress, a kind of auxiliary location structure is provided, make it can guarantee adjacent two segment arch case joint realization coupling, the accurately prefabricated location of the arch case pedestal of control arch case preparation joint precision.
The technical scheme that its technical problem that solves the utility model adopts is: the positioner that a special location arch case joint angle steel is set at two of prefabricated ground of arch case tire, utilize positioner will encircle the fixed-site of case joint angle steel by one-shot measurement, avoid repeatedly measurement and positioning arch case joint angle steel, improve the prefabricated precision of arch case, also improved effect simultaneously greatly.Be characterized in: form the portal frame positioning seat by concrete column and angle steel, pole, on concrete column, be embedded with steel plate, be fixed with the location angle steel on the steel plate, pole 4 and termination contact surface angle steel be welded into portal frame by bolt on the angle steel of location, so just form a firm positioning seat.Termination contact surface angle steel, install according to design inclination angle, arch case termination, to encircle case joint angle steel is connected on the contact surface angle steel of termination with bolt, play a part location arch case joint angle steel, that is to say, the inclination angle of the joint angle steel on the arch case and the design inclination angle of prefabricated positioning seat termination contact surface angle steel coincide, and so just can guarantee the precision of joint when two arch casees connect.
The beneficial effects of the utility model are, at arch tire two positioning seat are set, and make adjacent arch case sections joint realize coupling, avoided repeatedly measurement and positioning arch case joint angle steel, key issues such as arch section end position control are guaranteed to encircle case joint precision, thereby have been guaranteed construction quality.
Description of drawings
Fig. 1 is the prefabricated location of an arch case pedestal elevation.
Fig. 2 is that the B of Fig. 1 is to view.
Fig. 3 is that the C of Fig. 1 is to view.
Among the figure: 1. reinforced concrete post, 2. pre-embedded steel slab, 3. location angle steel, 4. pole angle steel, 5. termination contact surface angle steel, 6. bolt, 7. arch case joint angle steel, 8. arch case, 9. prefabricated ground of arch case tire, 10. ground.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in the figure, the frame type pedestal that the prefabricated location of arch case pedestal is made of concrete column and angle steel, by termination contact angle steel 5 and 7 couplings of arch case joint angle steel, concrete location pedestal is set at arch tire 9 two, prefabricated ground of case, location angle steel 3 is fixing with concrete column 1 by being welded on the pre-embedded steel slab 2, pole angle steel 4 is welded into a portal frame with termination contact surface angle steel 5 and fixes by bolt 6 and location angle steel 3, when arch case 8 is prefabricated, will encircles case joint angle steel 7 and be bolted on the termination contact surface angle steel 5 by bolt 6.The inclined plane that constituted of termination contact surface angle steel 5 keeps consistent with design inclination angle, arch case 8 terminations up and down, makes arch case 8 realize accurate the coupling in no support cable hoisting process, and the assurance contact surface is smooth, accurate.After arch case 8 prefabricated the finishing, remove bolt 6, just can take down the portal frame that pole angle steel 4 and termination contact surface angle steel 5 are formed, just can hang away arch case 8 then.
